Those are readers, correct. Bifocals have a distance and a reading component-much more complex (and expensive) to implement-only done by opticians.

I have used www.rxsportoptics.com several times in the past. Excellent service and a good product. Long established business
I'm a HUGE fan of Sea Vision. No bonded lenses or extra add-ins. They make new lenses to your prescription and replace the glass in your mask. I've started diving with bonded lenses and find Sea Visions's are much clearer and don't result in edges in the interior so they're easier to clean.
You can choose one of their skirts or send them your own two lens mask. I've sent them a few Tusa Ceos over the years (my eyes shift every 18 months or so) and I've always been happy with the turnaround time and cost.
The other difference is they calibrate the prescription and bifocal part for underwater use. They won't work above water but underwater your vision is perfect.
If you don't need the prescription for distance they also have 2x gauge readers with no upper lens correction. Still straight replacement lens so there's no bonding.
